22RE/Headgasket/timing chian/ oil leak

[Sudi]

Hello,

I purchased a 1994 toyota 22re pickup, it has 120K miles, I was told by the previous owner it uses a very little bit of coolant. When I went to change the oil for the first time it came out really thick and clumpy. I tapped up the coolant over flow and then I monitored the fluids. I had to tap up the overflow once a month and when it came time for the oil change I noticed a milky substance under the oil cap but the oil in the engine looked normal. When its cold I could see some vapor coming out the tail pipe and smell the sweet coolant smell. I installed new plugs, wires,pcv. I noticed the two plugs closest to the fire wall were corroded and the other two are fine, does that mean my head gasket is blow, what gasket should I use (oem)? Will I need a gasket set?

Am I better off pulling the engine to rebuild the head and replace the head gasket? Or should the engine be kept in the truck?

Are there difficult bolts to reach if it remains in the engine bay?

I am also starting to hear the timing chain clanking around for the first 5 seconds after startup and also everytime I change gears, its getting really bad so I stopped driving the truck. What is a good timing chain kit set that is relatively cheap but good quality I was told to
get ones with metal guides. Could I be mistaking a headgasket leak with coolant getting into the oil system from the timing cover being worn through?

I have a slight oil leak but not sure where its coming from I think its the valve cover gasket, any ideas, is this a common problem, only leaks when it sits for 8 hours or longer. It drips off the bell housing.

I am going to pull the oil pan to clean out the mesh on the oil pump pickup and make sure the broken timing chain guides are removed, do I need to buy a new oil pan gasket or can I use gasket maker? Removing the bar under the oil pan the only thing that needs to be removed before pulling off the oil pan?

I figure since I will be working on the engine should I replace the parts below and if so who has the best value?

oil pump
water pump
timing chain cover
fan clutch


I know this is a loaded post, I appreciate ya'lls help, I really like this truck, anxious to get it back on the road, definately a big improvement from my old truck GMC Sonoma.

thanks

That is a big post , well it does sound like the head gasket is leaking a little bit ,but I have seen trucks go a long time like that ,but as for replacement head gaskets I use felpro , Some people say use oem but I have never had any problems with felpro, as for timing sets I got one from dinosuar parts .com with metal guides , they do stop the timing cover from getting chewed up but you must have a good chain tensinor or you will still have problems, as for the oil pan gasket, I prefer to use a gasket rather than gasket maker , that has to be up to you , to remove the oil pan in a 2WD you must also drop the center link down . what I do is remove the pitman arm from the steering box and unbolt the idler arm from the frame so I don't risk damanging a boot on any of the center link connections .I hope I have'nt missed anything.

Well, if the truck has been driven with coolant in the crankcase for sometime, then I would seriously consider rebuilding the motor. The mixture of coolant and oil is very hard on the internal components i.e. bearings and such.

Change out the timing chain and guides. It would be a good idea to get the metal backed guides unlike the plastic ones that came from the factory.

When you pull the head, take it to a machine shop and have them deck the head for absolute straightness or the head gasket will go again. It may be a good idea to have it pressure checked (you can't maxnaflux aluminum) as well for any cracks. It isn't uncommon for these heads to develop cracks.

Here’s the guy to purchase the parts from. He is legendary when it comes to the 20r, 22r, and 22re motors.
